To all whom it may concern:

Be it known that LWILLIAu L. DrLLnA'v,

-a citizen of the United States,residing at Ko homo, in the county ofHoward and State of Indiana, haveinvented certain new and usefulImprovements in Cream-Separators, of which the followilu is aSpecification.

This invention rc ates' to centrifugal cream separators, and consistsessentially of an improved liner for the bowl, whereby separation of theconstituents of the whole milk is effected, and a lpeculiar compensatingbearing to take up t c great vibration incidental to the operation ofthe bowl when rotated, and which is adjustable by a special connectionbetween the stand of the machine and the casing of the bowl. I g

The invention also involves novel details of construction and for a fullunderstanding of the various novel features, reference is to be had tothe following description and the accompanying drawings, in which:

Figure 1 is a vertical sectional view of a separator embodying theessential features of the resent invention. Fig. 2 is a sectional viewon thelinc 22 of Fig. 1. Fig. 3

'is a side view of the liner forming a part of the invention, partly insection. Fig. l-is a vertical sectional view of the bearing for the bowlspindle. Y

Corresponding and like parts are referred to in all the views of thedrawings, and indicated by the same reference characters.

In carrying out the invention a machineconstructed .in accordancetherewith is comprised of the usual general arrangement of is peculiarlymounted on the standard 1.-

Said head comprises an approximately circular body having a cover 2removably mounted at one side thereof, said cover being form ed lwith anintegral arm 3 pr0\dded with .a'verti'ealbearing 4 at its inner end. Acrank shaft 5 1s IHOUIltCClJlI a horizontal.

bearing 6 provided in the upper ortion of the head 2, a suitable crankhand e 7 being applied to the outer end of the shaft 5 md a Jorge bevelgee-r8 being secured to the inner end of'snid shaft. The bevel ear 8meshes witha bevel pinion 9, the latter eingapart of a clutch element 10wlnch cooperates with a second clutch element 11 to provide a ballratchet mechanism, the balls being indicated at 12. The pinion 9 isadapted to be actuated on operation of the shaft 5 in an obvious mannerand the gearing mounted in the head 2 is designed to effect rotation ofa vertical shaft 13 which is arranged within the standard 1 and thenpperend of which is journaled' in the bearing 4 of the arm 3 beforedescribed.

The pinion 9 is loosely mounted upon theshaft 13 and the ratchetmechanism cooperatlng with saidpinion permits of continued rotation ofthe shaft even though the crank' handle 7-is stationary.

The head 2 is mounted on the standard 1 but is adjustable relativethereto in order that the osition of the crank handle 7 may be arjustedor.

varied according to the convenience of the operator. For the abovepurpose the upper portionof the standard 1 is I-Cul '6d in theower'portion of the head 2 and the latter is attached to the standard bymeans of a set screw 14 or analogous fastening. It will be apparent thatthe mounting of the head 2 is suchthat it may be rotated and-fixed in'anadjusted position with readiness. Upon the lower end of the shaft 13which extends into the base of the su ort 01: st and A is'mounted a gear15, a suite is adjustable bearing 16 being provided to receive the lowerex tremity of said shaft. The gear 15 meshes with a pinion 17 carried bya second gear 18 which-1s journaled in suitable bearings 19clearlyshown. The gear 18 engages a pinion 20 formed upon the lower endof the spindle 21 which carries the se arator bowl 22, the spindle 21being integra with the bottom of said bowl.

The bowl 22 is mounted for rotary move ment in the customary manner in apeculiar bearin which will be more clearly described hereinafter. Acasing 22, removably mounted upon its bottom 24, surroundsthe bowl 22.The bottom 24 of the cosin 23 is formed with an opening through whichthe spindle 21 passes, and projecting downwardly from said bott'ou is anannular internally threaded llange or collar 2-5 which is screwedupon-the upper end of a neck or not only detachably tubule projection 26cictc'ndiir upwardly from t e base A of the stand w iich carries the searator mechanism. The projection ZS-is ormed with an internal shoulder27 having an opening through which the spindle .21 passes and formedwith a'recess 28 in its upper side. Y

Arranged between the shoulder 27 of the projection 26 and the bottom ofthe bowl 19 casing 23 is a compensating bearing for the spindle 21, saidbearin being adjustable by relative adjustment or the bottom of the bowlcasing and the projection 26, such adjustment being allort ed ,by thethreaded connection between these parts. The coinpensating bearing abovementioned comprises a sleeve 29, snu ly receiving the spindle 21therein, and springs, 30 and 31. Intermediate of its ends the sleeve 29is formed with an integral flange 32 in tlie inper and lower sides ofwhich are provide circular grooves 33 in which theadjacent ends of thesprings and 31 arereceived. The low-er end of the 2,5 spring 3i isreceived in the recess 28 of the s oulder 27, andthe upper end of thespring 30 is received in a recess 34 formed in'the bottom .24 of thecasing 23 and at the )eriphery of the o enin of said bottom. 39 hesleeve. 29 is opsmafier diameter than the opening in the bottom 24 ofcasing 23 and passes through said openingl It will be apparent thatthe'arrangement of the parts oi the bearing just described is 35 suchthat the great vibration incidental'to the rotation of the bowl in theactual operation of the machine is fully absorbed, and strain and jarupon the supporting means for the bowl are reduced to a minimum.Furthermore the construction of the supporting parts of the compensatingbearing, whereby such parts also form supporting means'for the bowl is.extrcmely advantageous in that adjustment of said parts may be readilyeffected to correspondingly adjust the springs 30 and 31 whereby thetension of sa d springs may be increased or decreased as may benecessary under actual conditions of service. The casing23 surscrounding the bowl 22 is made of light metal and rests upon an annularshoulder formed in the outer portion of. the. bottom 24, being readilyremovable from such position.

Within the bowl 22 is arranged a peculiar form of liner, the specialconstruction of which is designed to increase the efiiciency of themachine with regard to the separation of the elements of the liquidoperated upon thereby. The liner is composed of a central stem 35 oftubular form, the lower end of which is' internally threaded to receivea threaded boss 36 which is integrally formed with the bottom of thebowl 22. The tubu-. lar stem35 is'tormcd with integral radially curvedplates or wings 36, the outer edge cooperating coileda spout 47. 7

pan 47 is provided, the latter being su 120 portions of whichsubstantially tit'thc inner sideof th'e bowl 22. The dates or wings 36arqintegrally formed at the lower portions thereof with the stem ortubular member 35, the inner edge portions of said plates being 'spaccdnearly throughout the length thereof from the members 35. In other wordsthe plates 36 are so formed as to provide an annular space'between theirinner edges and the tubular stem or member 35, said space comprising anupward passage for the cream as the latter is separated from the skim?milk. Between the several plates 36 of the liner are arranged atintervals, and vertically spaced from each other, a number of down- 3wardly inclining webs 37, sets of the webs being in parallei andsubstantially horizontal planes and having the inner edges thereofspaced from the tubular member 35,

or llusl. with the inner edges of the platesSG. 35 The several webs 37com rise transverse partitions between the bhu es or wings 36- and saidpartitions are straight in cross section or from. the outer to the inneredges thereof. Arranged at the up er portion of 9c the bowl 22 is thecover there or, said cover comprising inner and outer sections 38 and 39respectively. The outer section consists of a body receiving the upperend of the bowl and having a gasket 40 interposed bc tween it and theupper edge of said bowl.- The inner section 38 of the cover alsoconsistsof a body portion the same being spaced at its up )er side fromthecorresponding portion 0 the outer section of the cover to provide apassage 41 for the skim-milk which asses through a plurality of openings42 coated near the ed e portion of said inner cover section. Each of thecover sections has a tubular extension at its upper portion, theextension 33 of the inner section b ing spaced a-portion of its lengthfrom the extension 39 of the section 39, as shown at 41*, said spaceforming a continuation of the s ace or passage 41, and permitting theshim-milk to pass from t 1e passage 41 through outlet openin 43 in theouter cover section. A cream tn 0 44 is applied to the inner coversection 38 and conveys the cream passing upwardly from the space justsurroundin the stem 35, to the cream outlet 45. Mounts upon the top ofthe casing .23 for the bowl 22 is s rill; pan 46 from which leads In asimilar manner acream ported upon the pan -16 ahd receiving t c. creamfrom the cream outiit 4-3, A suit:- able spout 48 leads oi? irom'thc pan47. A cover 49 is provided for thc'pan47, cnd'h, float cup 50 is su in aconventional manner.

Itwill be undemtood that the stand for the separating mechanisni'beforcdescribed will have a suitable braeke tltntio carry the milkreceptacle-and may also ve a. cream reooorted upon said cover, 12 5,

latter having lateral openings 35 at its lower portion. The milk passesthrough the openings 35 and through vertical openings 37 in thelowermost webs 37 as well aspassing into the space between the member 35and the bowl by passage around the lower edges of the lowermost webs.The spindle 21 of the bowl 212 is provided with an adjustable bearing atits lower end as shown in the drawings and adjustment of said spindlemay be readily effected in the same manner as such adjustment may beperformed in outer section 39.

regard to the shaft 13 and the gear 18.

'The advantages of 'the several features of construction hereinbeforeset forth will be obvious from the foregoing description. A ring nut 51is screwed upon the upper extremity of the tubular member 35 of theliner and is arranged above the sections of the cover of the bowl 22.Said nut-engages the tubular extensions 39*" of section 39 and reventsdisplacement thereof from the owl and leakage of liquid therefrom at theouter flange 52 of the cover 39.

It will be observed that the upper portion 38 of the inner cover sectionhas a snug slid ing fit within the upper portion 39 of the outersection. Themilk holes 42 are located in the section 33 and the outletholes 43 in the Likewise the cream tube 44 is carried by he innersection and the upper end thereof must register'with the single outlethole -15. In order, therefore, to insure pro er registration of theseparts I provide a s ide groove u )on the inner surface of the extension39 an into which the tube 44 is received, the tube projectingsufficiently beyond the outer surface of the upper portion 38 to effectthis result, the hole 45 being at the upper end of the said roove.

It will be understood that the liner which -com )rises the wings 36rotates within the Patent ofthe United States, is:
